APPARATUS FOR MEASURING TILES.

Specification of Letters Patent.

Patented Dec. .5, 1911.

Application filed September 15, 1910. Serial No. 582,143.

To all whom it may concern:

Be it known that I, MAX RUDoLF DEGE- Low, a subject of the King ofPrussia, German Emperor, residing at Grohn, near Vegesack, in theKingdom of Prussia, Germany, have invented certain new and usefulImprovements in Apparatus for Measuring Tiles, of which the following isa specification.

The apparatus for measuring tiles is already very well known, that is tosay the apparatus in which the tile to be measured is placed in a framewhich indicates its dimensions. The tile is then stamped by hand withthe size indicated.

In the present invention this apparatus for measuring tiles and similarobjects is combined with an arrangement which measures and stamps thetiles at one and the same time.

The object of the invention is represented in the annexed design underthree different models.

Figure 1 is a side elevation of the machine. Fig. 2 is a section of thesame following the line 1-1 of Fig. 1. Fig. 3 shows a side elevation ofanother model of the machine. Fig. 4 is a third model. Fig. 5 is a planof Fig.4. Fig. 6 is a section of Fig. 4 along the line II-II. Fig. 7 isa section of Fig. 4 along the line IIIIII. Fig. 8 is a section of Fig. 7along the line IV-IV.

In each of these different models the ma chine comprises a frame 1, ofwhich the side 2 carries a support 3 which may consist of two shafts. Onthe frame 1 there is an indicating lever 5 turning on an axle 4, and bymeans of which the dimensions of the tile 7 are shown on the scale 6, tothis end the short arm 8 of the lever 5 is bent in the form of a hook.The lever is moreover made with a shoulder 9 situated under the axle 4and running in a grooved sliding piece 10. To measure the tile 7 it isplaced on the support 3 and held against the grooved sliding piece 10.The indicating lever is then turned on its axle 4 until the hook 8strikes against the upper end of the tile to be measured. The pointer ofthe lever 5 will then indicate the dimensions of the tile on the scale6. The tile is stamped with its size in the fol lowing manner. Ontheinside of the frame 1 are placed a certain number of keys 11 designed towork, by means of the bent levers 12 and the rods 13, the type levers14. Beingheld by springs the types 15 on levers '14 are continually incontact with the inking pads 16. These pads 16 are carried by a lever 17attached to the indicating lever 5 by a carrier spring 18 so that whenthe lever 5 is lifted it carries with it the lever of the inking padsand the types 15 are thus disengaged. By pressing the keys 11 whichcorrespond to the figures indicated by the lever 5 the type-carryinglever 14 is made to move and the types 15 strike against the back of thetile 7 through the slit 19. From the above it will be seen that themarking of the tile is not done automatically but depends on theoperator working the machine.

In Figs. 3 to 8 the stamping is done automatically. To attain this endan electromagnet is employed (Fig. 3). The plates 20 carrying thefigures of the scale 6 are isolated from one another and connected bythe wires 21 to the magnet 22, in the circuit of the magnet there hasbeen int-roduced a source of electricity 23 of any appropriateconstruction. There is of course a separate magnet for each of thefigure-plates 20. The points of the magnets carry each of them a figure25. The electric wire is connected with the indicating lever 5. Whenthis lever is in its normal position at rest the circuit is broken, butas soon as the lever comes in contact with one or other of thefigure-plates 20 a circuit is formed with the corresponding magnet,which, becoming magnetized draws its point 24 and stamps the plate inaccordance with the dimensions indicated by the lever 5. In order toprevent the formation of the circuit before the lever 5 comes intocontact with the figureplate 20 indicating the size of the tile, thefollowing precautions have been taken Fixed above the pivot of theindicating lever 5 is a plate 26 into which a bolt 28 is driven by theaction of a spring placed between the arms of a support 27 Above theplate 26 is a contact section 30 fixed on an insulating block 29 andconnected with the conductor 31.

The indicating lever 5 is made of a material which is a good conductorof electricity. As soon as the lever 5 is returned to its position ofrepose all the other parts of the mechanism return to their initialplaces, the type-carrying points being withdrawn by means of a spring 33or in any other appropriate manner.

In Figs. 4 to 8 the arrangement of the contact differs from that of Fig.3 in as much as the plate 26 and the spring 30 are each of themconnected to wires 34, 35. At its other extremity the conductor 34 isconnected with a commutator 36. The front end of lever falls into theslot 38 of a vertical rod 39 of which the shoulder 40 presses againstone of the arms of a bent lever 41 pivoted in a bracket 42 of thestandard 43. The other arm of this bent lever 41 passes through a slotin the horizontal plate 45 fixed on the two standards 43, 44, the upperextremity of the lever being caught in an opening 46 of the movable rod47 horizontally disposed. In this rod 47 is a slot 48 through whichpasses the vertical rod 39. The horizontal rod 47 carries a rod 49against which presses the spring 50 fixed on plate 45. The rod 49 islodged between the arms of the fork-like extremity 51 of a lever 52mounted on an axle 53. This axle is fixed on the point 54 of the magnet55. The axle 53 is fixed to the lever 52 in such a manner that when thelever swings the axle moves with it and displaces the point 54. To thelower arm 56 of the point 54 is fixed the lever 58 which controls thestamp 57. WVhen the rod 47 is displaced by the movement of theindicating lever 5 it causes lever 58 to swing and this last actsdirectly on the stamp 57. These stamps 57 are placed loose in a guidingpiece 59 each of the stamps is attached to a bent lever 60 connected bya bar 61 to a type-carrying lever 62. All these type-carrying levers aresubmitted to the action of a carrier spring 63. The normal position ofthe inking pad 65 is in front of the types 64 and it can turn around theshaft 66 set in arm 67 which is fixed to the frame 1. The magnet 55 isconnected with conductors 68, 69 one of which terminates in thecommutator 36.

In order to prevent the striking of a stamp which does not correspond tothe plate giving the size of the tile the lever 58 is provided (Fig. 8)with conical notches along its edges. The movable stamps 57 in theguiding piece 59 are also furnished with notches similar to those of thelever 58. The distance between the stamps 57 is slightly less than thewidth of the lever 58, the difference being however only a fraction of amillimeter. This arrangement insures the striking of the proper stamp.Let us suppose that the stamp lever, whose movement around the bolt 56is regulated by the amplitude of the rise in the indicating lever 5, isa trifle nearer the stamp (0) than the stamp (b) (Fig. 8) it will thenbe brought toward the stamp (a) by the conical notches 7 0. With thisarrangement it is absolutely impossible for two stamps to be strucksimultaneously. A spring 72 has also been fixed on the body 71 of themagnet (Fig. 7),

in order to facilitate the return'of lever 58 to its initial position.

' The working of the apparatus is as follows :The tile 7 3 to bemeasured, which is represented by the dotted line in Fig. 1, is

placed on the support 3. The grooved sliding piece 10 is then pushedalong by pressing against the tile the side 74 of the frame 1. This putsthe lever .5.in motion and its point rises until the hook v8 rests uponthe upper edge of the tile 7 3. The swinging movement of lever 5 causesthe bolt 28 to swing. likewise and that-in spite of the contrary action.

of its spring. This bolt 28 is thus brought into contact with the blade30. The distance between the upper edge 75 of the bolt 28 and the blade30 is equal to the distance'between the lower edge of the hook, 8 andthe lower edge 76 of the bolt 28. As soon as lever 5 begins to swing,the spring 77 withdraws the inking pad 65 from the types 64 which arethus liberated. The indicating lever 5 carries with it the rod 39'whosevertical movement is transformed by the transmitting mechanism into aswinging movement of lever 52 and through it to the stamp lever 58. Thislever 58 is thus brought above the stamp 57 corresponding to thedimensions of the tile to be measured. As soon as the lower edge of thehook 8 of lever 5 comes in contact with the upper edge of the tile 73,the bolt 28 touches the blade 30. As a result the electric circuitiscompleted and the magnet 55 electrified so that it attracts its point54 which at once acts upon the stamp.
